摘要： An oxide superconductor comprises a composition represented by the composition formula: (Ndx-Cey-Lz)2CuO4-d (wherein L is an element selected from Ca and Mg, and x + y + z = 1). The compositions of Nd, Ce and L of the oxide superconductor corresponds to a point falling inside an area of Nd-Ce-L ternary diagram surrounded by straight lines (A-B), (B-C), (C-D) and (D-A) connecting point (A) with point (B), point (B) with point (C), point (C) with point (D) and point (D) with point (A), respectively, the points (A), (B), (C) and (D) being points (x = 1, y = 0, z = 0), (x = 0.4, y = 0.6, z = 0), (x = 0.4, y = 0.3, z = 0.3) and (x = 0.1, y = 0, z = 0.9), respectively, in the Nd-Ce-L ternary diagram. Above-described Nd-Ce-L-Cu-O oxides can exhibit superconductivity within a wide range of composition when heat-treated in an atmosphere of nitrogen.

摘要： PURPOSE:To manufacture a thin superconductor film improved in critical current density by allowing plural gaseous raw materials to react with each other in a vapor phase under the conditions for accelerating the decomposition of bonding to ligands to form an intermediate film and then oxidizing the above intermediate film. CONSTITUTION:Ligand gases held in ligand vessels 11, 12, 13 are supplied on carrier gas into raw material vessels 1, 2, 3, respectively. Superconductor materials, such as Ba, Y, and Cu, in the raw material vessels 1, 2, 3 are formed into metallic complex gases under the heating conditions by means of heaters 8, respectively, and then supplied into a reaction vessel 5. A chemical reaction is allowed to occur in the reaction vessel 5 and the prescribed superconducting material is deposited on a substrate 9, by which a filmy intermediate is formed. The substrate 9 on which the intermediate film is formed is placed in an annealing furnace, etc., to undergo the oxidation of the intermediate film, by which the thin film of ceramics superconductor which is dense and practically in a chemically equilibrium weight state can be formed.

摘要： PURPOSE:To obtain the title superconductor through CVD process with enhanced film formation rate, causing no contamination with the carbon in the ligand, by making raw materials into ligand-contg. metal complex gases respectively and carrying out chemical reaction in the presence of both water vapor and oxygen. CONSTITUTION:A vaporized ligand (e.g. hexafluoroacetylacetone) is put into each of containers 11, 12, 13, while plural kinds of raw materials (e.g. Ba compound, Y compound, Cu compound) are pout into respective containers 1, 2, 3. Thence, the ligand in the containers 11, 12, 13 is transferred through a carrier gas (e.g. Ar) to the respective containers 1, 2, 3 followed by heating using respective heaters 8 to convert the raw materials into ligand-contg. metal complex gases, respectively, which are then introduced into a reaction chamber 5. Simultaneously, water vapor-contg. oxygen 10 is also introduced into said chamber 5 followed by heating the resultant mixed gas using a heater 8 to cause reactions, thus forming the objective filmy superconductor on a substrate 9.

摘要： PURPOSE:To make the captioned dynamic vibration reducer small and light while usable even under a high temperature by forming a vibration reducing body provided on a vibrating body in order to suppress vibration with a Zn-Al alloy having both spring function and damping function. CONSTITUTION:A vibration reducing body 12 is formed with a Zn-Al super plastic alloy (ZM-11, ZM-3, etc.) having a spring function and a damping function. This Zn-Al alloy has a higher heat resistance than that of rubber and a high strength while having a higher vibration reducing property than that of a cast iron, and greatly increases an internal friction value Q under a high temperature. For example, when this vibration reducing body 12 is supported by a fixed member 10 via a vibrating body 11 made of an iron plate and vibrated by means of a vibrating electromagnet 15 and, as the vibrating condition is measured by means of a pickup 17 and a vibrometer 18, it can be detected that a spring function and a damping function are sufficiently obtained. Also, when it is heated at 120 deg.C by means of a heater 14, a logarithmic decrement becomes approx. 5.7 times that at the time of free damping, greatly improving the characteristic under a high temperatures.

摘要： PURPOSE:To increase a film depositing rate, to Iower the reaction heating temperature and to improve the recovery of raw materials by providing within a reaction vessel a susceptor for holding substrates on which a reaction product of the raw gas is to be deposited, and an ultraviolet radiating means for radiating ultraviolet rays along and orthogonally to the flowing direction of the raw gas. CONSTITUTION:Within a reaction vessel 11, a substrate holding face 26 is provided on each of three side faces of a susceptor 25 inclined at the same angle with respect to the flowing direction of raw gas so that a plurality of substrates on which a reaction product of the raw gas is to be deposited are held on these holding faces 26. An ultraviolet ray source 30 is provided near the reaction vessel and ultraviolet rays therefrom are guided via a mirror 31 to a half mirror 32 by which they are divided into two parts. One part of the ultraviolet rays is guided via a mirror 33 to a window 14 from which it enters the reaction vessel along the flowing direction of the gas. The other part of the ultraviolet rays is guided to a group of half mirrors 34 provided corresponding to windows 19, whereby it is divided equally and introduced into the vessel orthogonally fo the axis of the vessel. In this manner, the reaction can be accelerated while the product can be prevented from being reacted again.
